The Guam Waterworks Authority will be conducting a smoke test on sewer lines in Barrigada on Wednesday, Jan. 3.

According to a press release, GWA crews will be conducting a smoke test on sewer lines along Route 10, near Wendy's in Barrigada, from 9 a.m. to 2 p.m. The test will help inspection crews locate breaks and defects in the sewer system.

Any smoke coming from vent stacks on houses or holes in the ground is harmless, odorless and is not a risk to humans or animals, according to GWA.

The smoke from the tests should not enter residents' homes, unless there is defective plumbing or dried drain traps. If smoke does enter residents' homes, GWA can be contacted on their hotline.
